My assistant can't read website URLs and phone numbers. It's buggy, stutters, and makes connections very poorly. Is there a solution for this? Do I have to go through the prompt? Or is there an option? I've already activated the read number box on vapi @Sahil @Shubham Bajaj @Vap#3739

Thanks for your message! To help you further, could you clarify which TTS provider and assistant configuration you’re using when the stuttering or buggy reading of URLs and phone numbers occurs? This will help identify if the issue is related to formatting, provider compatibility, or something else. If you have any specific error messages or examples of the problematic output, please share one for context.

Hey Ali, the issue you're experiencing is due to our phone number and website URL formatter being set up only for English. We're planning to add support for other languages in the next quarter. In the meantime, please instruct the LLM to respond in a readable format.

How can I instruct the LLM. I already instruct him by spelling each letter that I want him to read. But the pronunciation is not yet acceptable @Sahil @shubham.bajaj @Vapi

You will need to write the prompt related to it by providing the example how to send the output.

Hey Ali, checking if this is resolved/solved for you?

Not yet. Even when I spell the website and number in the prompt I still have issues. Maybe I need to use clone voice in Eleven Lab

To try a cloned ElevenLabs voice in Vapi, follow these steps: 1. Get an ElevenLabs API subscription and copy your API key from the ElevenLabs dashboard. 2. Go to the [Vapi Provider Key section](https://dashboard.vapi.ai/keys) and enter your ElevenLabs API key. 3. After syncing, select your cloned voice in the "voices" tab for your assistant. Tip: After setup, test your problematic URLs/phone numbers again to see if pronunciation improves.

Will a clone voice really improve the readable format for a website url and phone number ? @Sahil @Shubham Bajaj @User

A cloned ElevenLabs voice will not automatically improve the pronunciation or formatting of website URLs and phone numbers. The official documentation does not mention this as a benefit. For clearer TTS output, continue refining your prompts with explicit examples (e.g., "Please read the number as: one two three dash four five six...") and test different phrasings for best results. Tip: Use the [Prompting Guide](https://docs.vapi.ai/prompting-guide) to structure your instructions for improved clarity.

Yeah, but it is mostly related to how you send the data.

A cloned ElevenLabs voice will not automatically improve how URLs or phone numbers are read. For clearer TTS output, refine your prompt with explicit instructions. For example:

Please read the phone number as: one two three – four five six – seven eight nine zero. For the website, say: w w w dot example dot com.

Test different phrasings and use the [Prompting Guide](https://docs.vapi.ai/prompting-guide) for more tips. Sources: - [Set up a custom ElevenLabs voice in Vapi](https://docs.vapi.ai/customization/custom-voices/elevenlabs) - [Prompting guide](https://docs.vapi.ai/prompting-guide)
